She is shown on two bottles of MEIKO's sake: one labeled "重音てと", another labeled with her name in katakana, "重音テト"; she appears with Haku Yowane in another chapter.

Teto is a 31-year-old chimera girl who was born as a joke from NicoNicoDouga forum's users. She loves eating baguettes, and she has a close relation with Ted Kasane and Ruko Yowane.

Depicted as more innocent than Miku Hatsune is. Teto is cheerful and eager though may be naughty at times, perhaps inspired by her mischievous roots from Doraemon. Depicted also as a Tsundere, but to more gentler extent, unlike Neru Akita. She gets very angry or sad if someone has bread and does not share with her. Teto enjoys teasing people just to show she cares about them since she doesn't want to show her love. She can get out of control if not eaten bread for one day. Obviously, she doesn't act and sound for her age, for a 31-year-old girl, thus her human age is more believed; the depiction as a 31-year-old girl is often dismissed as artics from the users of vip@2ch. who created her. There are also persisting rumors of Teto's wings and a tail. She may or not be aware of her own Chimera form.
